Kalvin Ritter

Kalvin Ritter was a Barbadian member of the Yardbirds, a prominent group of jewel thieves that eventually disbanded due to a botched bank heist. Ritter was eventually assassinated by the ICA by a former client of his that was sold a counterfeit Gorka.

The Yardbirds
Though not much is known of Ritter's life before crime, however, it is known that he was discovered in the 1980's in London as a member of the Yardbirds, a group of jewel thieves ran by the mythical Serbian bank robber Aleksandr Kovac. Kovac became Ritter's mentor, teaching him the tricks and trades of the art of theft. Ritter adopted the moniker "Sparrow", to keep with the "theme" of the gang.

However, that all changed when Interpol placed a honeypot bank with millions of dollars worth of jewels inside. Upon their robbery, they were stormed by dozens of Interpol agents, though they fought their way out and went their separate ways after dividing the money they've stolen over the past decade.

The Sparrow
Kalvin Ritter emerged in the 1990's as a Florida-based art collector under his old nickname of "Sparrow". He stole countless artworks from many an individual. Ritter eventually retired as a cat burglar, due to theft becoming more digital than analog. Unfortunately for him, he sold a client a counterfeit Gorka, which drove that client to contact the ICA to put a hit out on Kalvin Ritter.

In 1998, Agent Darius LeVan accepted the contract, and infiltrated Ritter's yacht in Sydney, Australia. He snuck aboard the ship, eventually disguising himself as a yacht crew member. LeVan then shot Kalvin through the head with a silenced pistol, killing him. He then made his escape casually, not being found out by any individual.

Personality and skills
Ritter was known for switching personalities in the blink of an eye, lacking any and all empathy while on the job. He was also flexible, acrobatic, and extremely charismatic.
